As shown in fig. 6 to 8, an embodiment of the present application further provides a control method of an electronic device, where the electronic device is the electronic device described above.

The electronic device may be an electronic device such as a smart phone, a tablet computer, an electronic book reader, a wearable smart device (e.g., a smart watch), an electronic game machine, and the like, and the application does not specifically limit the type of the electronic device.

The control method comprises the following steps:

s100, receiving a first input of a user, wherein the first input is projection of a projection object;

s200, controlling the projection assembly 300 to start, and projecting the projection object onto a screen outside the equipment shell 100;

s300, receiving a second input of the user, wherein the second input is the definition adjustment;

s400, the first housing part 110 and the second housing part 120 are controlled to be relatively close to or relatively far away from each other to adjust the distance between the convex lens 330 and the imaging device 320.

For example, when a user operates a document on a display screen of the electronic device, the display interface has a projected virtual key, and the user clicks the virtual key to input a first input to the electronic device, and after receiving the first input, the electronic device controls the projection assembly 300 to start, and projects a projection object onto a screen outside the device housing 100.

The electronic device controls the projection assembly 300 to start, project the projection object onto the screen outside the device housing 100, and simultaneously displays virtual keys appearing on the display interface, which adjust the definition, such as "up, down, left, and right" icons, and the user clicks the virtual keys, which are the second input to the electronic device, and after the electronic device receives the second input from the user, the electronic device controls the first housing part 110 and the second housing part 120 to be relatively close to or relatively far away from each other, so as to adjust the distance between the convex lens 330 and the imaging device 320. For example, clicking the "up" icon controls the first housing portion 110 and the second housing portion 120 to be relatively close together, and clicking the "down" icon controls the first housing portion 110 and the second housing portion 120 to be relatively far apart.

When the second input is a long press operation, the first housing part 110 and the second housing part 120 are controlled to relatively approach or relatively separate at a first speed; when the second input is a click operation, the first housing part 110 and the second housing part 120 are controlled to relatively approach or relatively separate from each other at a second speed; the first speed is greater than the second speed. When the projection object projected onto the screen outside the apparatus housing 100 is blurred after the projection assembly 300 is activated, the adjustment distance is long, and thus the adjustment time can be saved by quickly adjusting the first housing part 110 and the second housing part 120 to be relatively close to or relatively far away from each other. When the projection object projected onto the screen outside the apparatus housing 100 after the projection assembly 300 is activated is not very blurred, the distance to be adjusted is short and only fine adjustment is required, so that the sharpness can be accurately adjusted by adjusting the first housing part 110 and the second housing part 120 relatively close to or relatively far away from each other by reducing the speed.

By adopting the control method of the electronic equipment, the objects such as documents and images in the electronic equipment can be conveniently projected onto the screen outside the electronic equipment through the projection component 300 of the electronic equipment, so that the objects such as documents and images in the electronic equipment can be conveniently shared and displayed; the distance between the convex lens 330 and the imaging device 320 can be adjusted by adjusting the relative movement of the first housing part 110 and the second housing part 120, the housing parts which can move relative to each other in the electronic device are fully utilized to realize the adjustment of the object distance and/or the image distance in the projection assembly 300, no additional adjustment component of the projection assembly 300 is needed, the number of components can be reduced, and the structure of the projection assembly 300 is simplified; the relative movement of the first housing part 110 and the second housing part 120 may not only serve as an adjustment member of the projection assembly 300, but also provide a space for adjustment of the projection assembly 300; the object distance and/or the image distance of the projection assembly 300 can be adjusted, so that the projection definition can be adjusted, and the user experience is improved.
